H = HIGH Voltage Level. L = LOW Voltage Level. X = Don’t Care.Z = HIGH Impedance.
Operation beyond the limits set forth may impair the useful life of the device. Unless noted, these limits are over the operating free-air temperature range.
Unused inputs must always be connected to an appropriate logic voltage level, preferably either V
CC
or ground.
Typical values are at V
= 5.0V, T
= +25C ambient.
This parameter is specified but not tested.
Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample
and hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting of
a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametric tests. In any sequence of parameter
tests, I
tests should be performed last.
Tested at +25C.
